Overview
This Mirafone Model 1346 marching valve trombone, often referred to as a flugabone, represents an interesting period in brass instrument design during the late 1960s through the mid-1970s. Instruments like this were developed to serve the growing American marching band and drum corps market, where a compact valve instrument could replace the traditional slide trombone on the field.
The Mirafone 1346 features a compact trumpet-style wrap with three top-action piston valves and a large yellow brass bell measuring approximately 8.25 inches. Compared to many bass trumpets or marching trombones of the same era, the larger bell produces a broader and more resonant sound that sits comfortably within the trombone family.
Unlike many German orchestral instruments from Miraphone’s rotary tradition, the 1300-series marching instruments used piston valves, reflecting the preferences of American band programs during this period. The instrument accepts a small shank trombone mouthpiece, which allows trombonists to transition easily to a valve format while maintaining a familiar sound concept.
Because of its design and tonal profile, the Mirafone 1346 occupies an interesting space between marching valve trombone, flugabone, and bass trumpet, offering a compact valve instrument with a distinctly trombone-like voice.
Player Perspective
From a playing standpoint, the Mirafone 1346 feels immediately comfortable for trombonists. The small shank trombone mouthpiece receiver allows players to use their normal mouthpiece setup, and the instrument responds with a tone that is much closer to a flugabone or valve trombone than to the tighter and brighter sound of many bass trumpets.
The larger bell contributes to a fuller and more rounded sound, giving the instrument a broader tonal footprint that works well in brass ensembles, commercial settings, and experimental brass textures. Players exploring vintage marching brass, studio doubling instruments, or compact valve alternatives to the slide trombone may find this design particularly appealing.
Because of its balance of agility and low brass character, the Mirafone 1346 can function effectively in jazz sections, brass ensembles, theater orchestras, and studio work, especially for players who prefer valve technique while maintaining a trombone mouthpiece setup.
Questions Players Often Ask
What is a flugabone or marching valve trombone?
A flugabone is a compact valve instrument designed to replace the slide trombone in marching settings. It uses piston valves and a small shank trombone mouthpiece while maintaining a tonal concept similar to a tenor trombone.
Is this instrument the same as a bass trumpet?
Not exactly. While it may appear similar to a bass trumpet, the larger bell and trombone mouthpiece receiver give it a broader, more trombone-like sound. Many players describe it as sitting somewhere between a bass trumpet, flugabone, and valve trombone.
What mouthpiece does the Mirafone 1346 use?
This instrument accepts a small shank trombone mouthpiece, which makes it particularly convenient for trombonists. A standard Bach small shank fits perfectly- not included.
Condition Summary
This vintage Mirafone 1346 is in good overall playing condition and has not recently undergone a full shop service or chemical bath. The valves function properly and the instrument plays well as it sits.
Cosmetically, the horn shows typical signs of age but no major dents or structural damage. The bell flare has a few minor imperfections consistent with light contact from items such as mutes or possibly a trombone stand, but these are not dents or significant damage.
The piston valves show some minor surface marks consistent with an older instrument that has spent extended time idle. These are not severe plating loss areas and have been lightly buffed to smooth the surfaces. The valve springs remain very strong, and when properly lubricated the valves operate normally. Any minor surface imperfections are not noticeable during playing, and the instrument remains a solid, functional performer.
There is also a small solder spot visible on one of the outer brass tubes, visible in the photos. This does not appear to be a structural repair or patch. It may be the remnant of a small attachment point, possibly related to a music holder or accessory mount, although further comparison with period Mirafone examples would be required to confirm this detail.
The instrument includes the original fitted hard case.
This vintage Mirafone 1346 offers a fascinating example of the marching valve trombone / flugabone design era, combining the tonal character of the trombone with the compact agility of piston valves. For players interested in vintage brass, studio doubling instruments, or alternative valve trombone concepts, it represents a unique and very playable instrument from Mirafone’s export period.
